Does a car need to undergo on-site inspection in its sixth year?

Vehicles in their sixth year require on-site annual inspection. Below is relevant information about vehicle annual inspections: 1. The six-year exemption from inspection applies to non-commercial passenger cars and other small and mini passenger vehicles (excluding vans and vehicles with 7 or more seats), which are exempt from on-site inspection within six years. 2. However, owners still need to periodically apply for the annual inspection sticker. In the second and fourth years after purchasing a new car, owners must bring the vehicle registration certificate and valid compulsory traffic insurance policy to the vehicle management office to apply for the inspection sticker. Alternatively, they can apply for the annual inspection sticker online and choose to have it delivered by courier. 3. Before the sixth-year inspection deadline, owners need to take the vehicle to an inspection station for on-site testing. Upon passing the inspection, they can obtain the annual inspection sticker. If a vehicle fails to obtain a valid inspection sticker within three consecutive inspection cycles after the inspection validity period expires, it will be subject to mandatory scrapping.

What is the difference between turbocharging and naturally aspirated engines?

Here are the differences between turbocharging and naturally aspirated engines: 1. Different engine structures: A car's turbocharged engine adds a turbocharging device to the traditional engine, while a naturally aspirated engine does not have this device. 2. Different power outputs: A turbocharged engine of the same displacement can have a power performance that is more than 40% higher than a naturally aspirated engine, meaning the same engine can output greater power after turbocharging. In other words, under the same displacement, a turbocharged engine provides more explosive power than a naturally aspirated engine. 3. Different maintenance costs: A turbocharged engine, with its stronger power, tends to experience performance degradation faster than a naturally aspirated engine, leading to higher maintenance costs in the long run. On the other hand, a naturally aspirated engine, without the intense pressurization of turbocharging, degrades more slowly and has relatively lower maintenance costs.

What Causes a Muffled Engine Sound?

Engine sound becoming muffled may be caused by abnormal cylinder operation, throttle opening issues, or severe carbon buildup. The reasons for a muffled engine sound are as follows: 1. Check the gasoline filter, clean the fuel injectors, and ensure the fuel supply meets the required standards. 2. Inspect whether the air filter is dirty, if the vacuum tube is aged or leaking, and clean the throttle, as these can affect the air intake volume. 3. Check if the three-way catalytic converter is clogged, which can impact exhaust flow. It is recommended to clean or replace it. 4. Verify if the engine cylinder pressure meets the standard, which should be above 8 kg. 5. Check whether the replaced engine oil is of the correct grade. Using oil with too high a grade or overfilling the oil can both lead to a muffled engine sound.

What is the difference between body-on-frame and unibody?

The difference between body-on-frame and unibody lies in their structural designs: A unibody structure, as the name suggests, is designed to bear the weight of automotive components such as the engine, transmission, suspension, etc. These parts are directly mounted onto the vehicle body, forming an integrated whole. On the other hand, a body-on-frame structure retains the traditional chassis frame. Automotive components like the engine and transmission are mounted on the chassis frame, while the body itself does not bear these parts. Below are the advantages of both body-on-frame and unibody structures: I. Advantages of unibody structure: 1. Compared to body-on-frame, unibody structures are generally lighter in weight due to the absence of a frame, resulting in better fuel efficiency and a relatively lower center of gravity. 2. In the event of a collision, the front and rear frames of a unibody structure are designed to crumple, absorbing impact forces to protect occupants, making it relatively safer. II. Advantages of body-on-frame structure: 1. When encountering rough terrain, the highly rigid chassis frame of a body-on-frame vehicle can effectively absorb and resist torsional forces, significantly reducing the impact on the body. 2. Since the chassis frame and body are separate and often contain damping materials in between, there are fewer rattles when driving on complex road conditions. 3. With components mounted on the chassis frame, maintenance and replacement tasks are more convenient.

How to Remove Fog from Car Windows?

Methods for defogging car windows are as follows: 1. Cold Air: The most common method is to turn on the AC cooling switch + maximum airflow to the front windshield + external circulation (if the humidity outside is higher than inside, internal circulation is recommended). This method works the fastest. 2. Rear Window Heating Wire + Rear Wiper: Almost all cars now have a "rear window heating" function. Its advantage is that it melts snow and removes fog. During rain, it can be turned on along with the rear wiper for better results. 3. Wiping the Inside of the Window with Windshield Washer Fluid: This is a convenient method when outdoors. Use a towel dampened with windshield washer fluid to wipe the inside of the front windshield, the four side windows, and the left and right rearview mirrors. It's advisable to keep a bottle of windshield washer fluid in the car trunk for emergencies. However, the effect doesn't last long, so it should be used in conjunction with the air conditioning for sustained defogging. 4. In cases of light fog, you can slightly open both windows to allow air convection.

Should You Pull Out a Nail from Your Tire?

Do not immediately pull out a nail from your tire. Here are some relevant guidelines when dealing with a nail in your tire: 1. Stay where you are and either replace the tire with a spare or call for roadside assistance. 2. Remember, if the tire sidewall is punctured, it cannot be repaired—you must replace it with a spare or call for help. 3. Tire leaks can be categorized as rapid or slow, requiring different responses based on severity. 4. Rapid leak: Under no circumstances should you continue driving, as this can ruin the entire tire and poses extreme danger to the driver. Stop immediately and replace the tire with a spare. 5. Slow leak: You may drive slowly to a repair shop. However, avoid high speeds or long distances and monitor tire pressure constantly. It’s also advisable to carry a portable air pump in your car to maintain tire pressure until you reach a repair shop.
